My wife returned to college to pursue a new career in medical lab science. She had been using an old TI 83+ for statistics classes, but it had become unreliable- losing battery contacts in the middle of a test. So, when she needed this for a pre-calc course, I bought one at Staples. The calculator is remarkable-turns on and off as it is supposed to, perfomrs calculations reliably, and the batteries last in this new model. No dropouts. It does everything my wife can ask of it, and it should last her the bulkof her professional life. (we do want to retire in a few years!) Thanks, Staples!

My daughter is using her new calculator daily. She is learning geometry in 8th grade. She learned how to use all the function keys after studying it for a little bit. It helps her graph the functions nicely. This will be the last calculator I will need to buy her for high school and her college years with sophisticated math functions.

Pretty much the best retail price around from a store.BE careful to check the Staples sight first because on line it is cheaper then the store and you must ask them to give you the better price.It was a purchase for my son's class.They are locked up in the back room and must be persistent to have an associate find it, some want to go back and tell you there aren't any more even though the system shows that there are some in inventory.

My oldest son has used this thru his entire high school math class and it a great tool. We were just talking the other day that it has not yet needed its battery changed. It will be going off to college with him in the fall. That being said my other son has just requested the tu 83 for his high school math classes. Someone else told me to get this other brand because it was cheaper. She said she has bought a few and they worked well. I asked her why she bought a couple since she has a kid the same age as my oldest and she said it wore out. So based on that I bought the ti83 again for my second son. Enough said
